Using one of my sketches, I added strong color by painting in Painstorm, and then added tone, depth, and lighting effects in iColorama. I use Paintstorm only for painting, and the painted output needs punching up. iColorama is ideal for this. The additional finishing I was able to do in iColorama give a 3D feel to this colorful image.
I started by photographing this sketch of mine. These were actually two sketches I did of the same live model, on the same piece of paper. I cleaned up the photo in iColorama using Form/Unperspec to straighten the paper, and Form/Crop, and Adjust/Levels to increase contrast and whiten the paper.
I opened the cleaned-up image in Paintstorm Studio Pro. On a new layer, I used the Big Watercolor brush to paint color on the figures. I moved the sketch layer to the top and changed its blend mode to Multiply, so the sketches lines are visible over the paint.
On another new layer, I selected a background color and used the paint bucket to fill the layer with it. I moved the background layer to the bottom of the layer stack so that it doesn't obscure any other image elements. Then on another new layer, I used the Big Watercolor brush to paint a white ground around the figures. I placed this layer directly above the background fill layer.
I changed the color of the fill layer by selecting another color and using the paint bucket to fill the layer with it.
On a new layer, I painted some highlights using the Big Watercolor brush. I placed the highlights layer under the sketch layer and above the figures layer.
On another new layer, I used the Demo Gold Strips brush to paint a texture.
I moved the texture layer to below the figures layer so that it doesn't obscure the figures. Both the texture and the ground serve to hold the two figures together.
On a new layer, I painted a white border using the Big Watercolor brush. I placed this layer below the figures layer and above the texture layer.
Here are my layers. I named them for future reference, and saved to my camera roll. I always also save a psd file, with all the layers, to iCloud.
I opened the saved cameral roll image in iColorama and used Effect/Raise preset 1 at low opacity, for a touch of emphasis.
I brightened the image and added contrast using Adjust/Levels.
I used Texture/Leak to add a lighting effect, resizing and repositioning the lighting effect using my two fingers, and I used a brush mask to apply the effect only where I wanted it. As a final touch, I created a drop shadow around the figures, using a method I describe here.
